RE: Spektrum DX18

Thank you all so much, your answers helped out a great deal. I have just started getting the gist behind it. It's probably easier to start anew from the rx, rather then what I was doing, trying to minimize alteration in the set up, just in case if I decide to go back to the 12x. But after playing with it some more, I think I'm liking the 18 pretty good and probably wouldn't worry about going back.

RE: Spektrum DX18

Barry, I know exactly what you mean, I admit to thinking like you were, I was a bit annoyed that the thing was swiping my gear channel, how dare it!
Eventually the logic dawns and you suddenly realise that this is a really clever bit of kit left to it's own devices, it took me time.
It can be disconcerting when you are reprogramming your fleet of finely honed complex jets to a new system but of course you always have your base settings, throws etc. to copy from your old transmitter.
I found it a learning curve well worthwhile pursuing, I'm sure you will also, glad you feel happier.
Gary.

Hey Gents

There's a wealth of information being passed in this thread. For those of you who do a lot of programming, most of this makes sense. For guys like me, I struggle. You all know how difficult searching threads and finding what you read some time ago can be.

One of you take the initiative and create an ebook. Maybe even make it a collaborative effort. I know at least one who would get one for his Kindle. I'm sure many more would. The information could be used to help DX8 users as well and I'd be happy to pay for it.

Β*Hi guys,
im setting up a Bobcat with the Spektrum 18X and a Β*Spektrum12020 receiver, TM1000
power supply is thru a Powerbox Gemini with 2 x 2300 mA LiFe packs.
ive plugged the TM1000 telemetry module into the data/bind port and batt 1 into batt port and batt2 into the srxl port
Ive selected the Powerbox option on the transmitter telemetry menu , but I get only a single battery voltage readout.
there is a single Rx batt voltage option with alarm options which I can't ddisable how do I get both pack voltages on my Tx ?

you cant.. its nominal bus voltage... you can hook separate volt wire to a separate source like turbine batt.

RE: Spektrum DX18

We will all get thru the programming woes as we learn.. just remember the twin polarity link.. that alone is worth the price of the upgrade.. I am not looking back.. my numbers have improved dramatically on my receivers..

Dustin has begin to put together a categorical listing of DX18 topics here.. check it out....

RE: Spektrum DX18

Guys,
i am looking for a new radio, since i will start flying jets soon.
I have an old jr 9303 2.4 and 6-7 RX, but want somthing new.
I really liked the dx 18, since i can use my Rx. with it, but i saw, somewhere, that it may has some range problems and some glitches in the screen.
Do you have any issues with it?
Should i go with it, or maybe get a 12x?
I don't want to start a brad war here, just wanna know what is better for me and for my $$ jets.
Thanks.

Go with the DX-18. I'm not aware of any screen glitches.

The 12x is an excellent transmitter but it is beginning to show its age in terms of features. It doesn't have a lot of the things found on the DX-18 like a memory card, and on-line firmware upgrades to name just a couple.

The DX-18 has the best range of any spread spectrum Tx that I've seen. The crossed antennas on the transmitter really cut down on signal fades. The standard Spektrum/JR DSM2/DSMX transmitters have excellent range due to the signal processing gain from the DSSS processing algorithm, but the DX-18 with the crossed Tx antennas is even better. Many folks with DataLoggers have noted this.

(PS. I'm not affiliated with JR/Horizon/Spektrum in any way and also am not interested in starting a brand war. If you like Futaba stuff, stick with it.)

RE: Spektrum DX18

w4sm Thanks for the answer, it was very hopeful.
This is what i am looking here, pro and cons from this brands, without a war.
I didn`t know that the dx 18 has the best range, even better then the new jr xg11?

I don't know much about the new JR XG series. As best I can tell their modulation system (DMSS) is very similar to DSMX but is not compatible with it. If you have a lot of Spektrum receivers, old JR DSM2/DSMX receivers, or Horizon/Parkzone bind and fly models, none of these will be compatible with the new JR XG (DMSS) radios. The only other issue is that JR cannot use separate remote receivers as Spekrum holds the patent on these. That's probably not a big problem. Again, I'm not trying to start an argument here. Futaba seems to work OK without remote receivers, but I'm personally a fan of them, especially in planes with a lot of internal metal, like turbines.

Frankly, I'm at a loss for why JR has abandoned DSMX, at least in the U.S. Because of the huge micro bind and fly Horizon market and the large amount of Spektrum 2.4 GHz equipment already in use (and incompatible with the new JR systems), this is REALLY going to affect their U.S. sales. I'm sure there's a story there between Horizon and JR, but we'll probably never know the details. I could GUESS that on one hand JR was tired of paying Horizon royalties to use DSMX and on the other hand, Horizon was tired of JR's reluctance to meet their requests for new features....

RE: Spektrum DX18

Slightly irritating an updated DX18 comes out 3 months after I got this one. Not bothered by the QQ labelling all over it...I can live without that but I read there are improved ergonomics and programming. Sucks if we can't upgrade DX18 to those. e.g. 3 servo per wing matching?

RE: Spektrum DX18

ORIGINAL: John Redman

@ Rob, you get 22 ms or 2048 resolution when using 12 channels on a 12 channel receiver.

No improved ergonomics on the 18QQ transmitter. Same case and special programming.

Johnny,

What about that special programming, we were all sold on the fact that the DX18 would be software updatable. Even if the software was a small fee I don't think that so many of us would be feeling a little violated right now....

OK. Take your word for it John. I mis-interpreted this then "The Special, limited edition DX18QQ Somenzini radio from Spektrum takes the already acclaimed DX18 platform to new heights, offering R/C pilots the very best in control, ergonomics and features as specified and tuned by Quique himself."

Wouldn't mind one of those "Sol de Mayo Transmitter Case"? Can we get those separatley? The regular Spektrum stand up cases don't accomodate the height of the DX18.

RE: Spektrum DX18

Question for John R........

Are you able to transfer models to the QQ using an SD export/import from my naked 18 or is there an incompatibility associated with software differences on the QQ......hope so as I just completed moving 8 planes from my 12 X.....a bit of a PITA..

RE: Spektrum DX18

while we are talking programming.. V1.03 is out for a bit now.. with V1.02, I began to see improvement to antenna counts.. of course hard to quantify, but it seemed to improve a bit on both modulations.. There must have been a small RF tweak to it over V1.01.
